Some women have red faces on a constant basis.

This is sometimes due to climate, temperature, allergies, sensitive skin, her skincare treatment, etc.

Keeping this in mind, don’t jump into conclusions when a girl’s face blushes as you are talking to her.

This isn’t an instant sign that she is into you.

A face is blushing when it turns red due to increased blood flow to the face.

This is triggered by nerves in the sympathetic nervous system that force blood vessels to open wide, and get filled with blood.

The enlarged blood vessels that result from this makes the skin appear flushed and red.

Yes, this reaction can occur when a girl is into a guy and her nerves are running riot.

However, it can be triggered by a litany of reasons as aforementioned as well.

To know for sure that she was blushing due to you, further investigation is required.

For one, observe her whenever she isn’t aware of your presence.

As she is walking about, what does her face look like?

As she is talking to people, what does her face look like?

If her face is clear and normal in these instances, it means that her face is usually clear as she is going about her day and talking to people.

This is your first solid sign that her face isn’t perennially flushing.

Alright, don’t celebrate quite yet.

Her face was blushing when you were talking to her, but there are other reasons why this happened that are worth considering.

Was there an embarrassing moment from her past that occurred while you were present?

In that case, the sight of you triggered that embarrassing memory, and as you were talking to her, she was incapable of keeping her light skin from blushing.

She was remembering that embarrassing moment and how self-conscious she felt when it occurred.

Besides embarrassment, a girl blushes when she is frightened.

Yes, fright does cause blushing.

Is there something about you that is scary or intimidating?

Do you make people frightened in your presence, especially those smaller than you in size?

Like every human being, she has a biologically instinctive fight or flight mode that is involuntarily activated by her sympathetic nervous system whenever she feels a sense of danger or fear.

Her blood vessels widen, filling up with blood, and a flushed facial appearance ensues.

Do you instigate fear in people, or women in particular?

If you don’t, you have eliminated the likelihood that she was blushing out of fear.

There is one final test.

Was this the first and only time you have observed her blushing as you were talking to her?

In that case, this isn’t enough.

She has to blush again.

In blushing again, she would be showing that the first time she did it with you wasn’t a fluke.

The next time you talk to her, pay attention to whether she is blushing again.

Supposing she is, this is your final confirmation that she is into you.
